Washing up liquid Fairy Platinum and detergent Persil are on the list of banned products, as is Palmolive Natural soap.

"We believe Fairy Platinum is in compliance with the regulations in Russia and are seeking to work with [the Russian agency] to resolve this matter as quickly as possible," said Procter & Gamble spokeswoman Marina Barker.

The companies hit by the announcement have factories in Russia, but some of the products are also imported.

The Russian watchdog said it would be inspecting Henkel's factory in the city of Perm.

"We are seeking dialogue with the relevant authorities to understand the background of their measures," said Henkel spokesman Sanjay Mistry.

Moscow banned most food imports from the U.S., European Union, and other countries last year, in retaliation for Western sanctions imposed over Russia's role in the crisis in Ukraine. Russia recently added Dutch flowers to the list of banned products -- citing safety concerns -- and extended the embargo until 2016.
